TYPE OF EXPANSION JOINTS

STANDARD - Single arch for use where initial misalignment of two pipes to be connected does not exceed 1.8", but not where flanges are out of parallel. Available for pressure or vacuum. Arch can be filled, however, 
movement limitations are reduced 50%

MULTIPLE ARCH - Standard joint with 
2 or 3 arches.  Recommended for 
greater movement where face to face 
dimensions are not limited.  Suitable for 
pressure or vacuum applications with 
flanges or sleeve ends.

LIGHT WEIGHT -  Recommended for handling air, liquid, gases and fumes at 7.5 ( 15"vacuum absolute ) to 
15 psi. Available with multiple arches, filled arches and sleeves ends.

RETAINING RINGS -  
Use of split-steel  rings assure a pressure-tight seal.  Outside diameter is same as standard flange and contains the same number of bolt holes.  Those used on joint sizes upto 40" are two-piece ( 4 segments  per joint ). Four-piece rings ( 8 segments per joint ) are used on all larger sizes.  All are generally 3.8" thick.
